Results are presented for an experimental study of Taylor vortices and turbulence in the flow between a rotating inner cylinder and both concentric and eccentric stationary outer cylinders. The results include: 1). measurement of the critical speed for onset of Taylor vortices as function of the eccentricity of the cylinders, 2). visual study of the flow up to a Reynolds number of 40,000, 3). measurement of the friction factor for the flow up to a Reynolds number of number of 40,000, 4). study of the effect of axial flow on the critical speed for onset of Taylor vortices. 5). preparation of design charts for calculating friction loss in concentric and eccentric journal bearings, operating in super-laminar flow regime.--Author.

Seldom does a physical system, particularly one as apparently simple as the flow of a Newtonian fluid between concentric rotating cylinders, retain the interest of scientists, applied mathematicians and engineers for very long. Yet, as this volume goes to press it has been nearly 70 years since G. I. Taylor's outstanding experimental and theoretical study of the linear stability of this flow was published, and a century since the first experiments were performed on rotating cylinder viscometers. Since then, the study of this system has progressed enormously, but new features of the flow patterns are still being uncovered. Interesting variations on the basic system abound. Connections with open flows are being made. More complex fluids are used in some experiments. The vigor of the research going on in this particular example of nonequilibrium systems was very apparent at the NATO Advanced Research Workshop on "Ordered and Turbulent Patterns in Taylor Couette Flow," held in Columbus, Ohio, USA May 22-24, 1991. A primary goal of this ARW was to bring together those interested in pattern formation in the classic Taylor Couette problem with those looking at variations on the basic system and with those interested in related systems, in order to better define the interesting areas for the future, the open questions, and the features common (and not common) to closed and open systems. This volume contains many of the contributions presented during the workshop.
